Abstract

A process for removing contaminants, containing at least one metal selected from the group consisting of iron, nickel, cobalt, aluminum, and lithium, from a polymer, a process comprising (A) treating the polymer in a water immiscible solvent with a oxidant, and then, or at the same time, or later (B) treating the polymer with an aqueous solution of citric acid, and then (C) removing the metallic contaminants separating the aqueous phase from the polymer.
